“Have you ever wished you knew how to easily add questions into a video to create lesson content or to help ensure that students are engaging with video content? Well, you can, for free!”
I like the idea of being able to insert questions and comments into videos that will be used with students, either large group or individual. It provides for formative quick checks to ensure students are on track and can generate discussions amongst groups or with the whole class. I also think that, giving students this option, they could create reactions by asking questions and direct their own learning through adding questions or comments to what they are viewing.
